Magnetic sensitivity

The trend towards miniaturization continues. The original reed switch is getting continually smaller and therefore can be integrated at minimal space. Its magnetic sensitivity has been improved and stabilized. New materials allow the use of even smaller magnets without reducing the distance between reed switch and magnet.

Study of the V-typc sample (Table 2) has shown that D, D2, and D3 doses inhibit cell growth by 9.7, 18.6, and 24.2%, respectively. This is close to the effect of Platidiam Ptd-L solution from which the drug adsorption was carried out. Results obtained show that almost all Platidiam is released from the magnetically sensitive carrier into the cultivated medium. Increased cytostatic action of magnetically sensitive nanocomposites (Platidiam carriers) may be achieved by means of solvent, adsorption time, and temperature optimization. 

Magneto-optical disks (MODs) are rewritable, and operate differently than either ROM or WORM disks. Data is not recorded as distortions of a thermally sensitive layer within the disk. Rather, it is written using combined magnetic and optical techniques. Digital data consisting of Is and Os is encoded in the optical signal from the laser in the usual manner. Unlike the ROM or WORM disks, however, the MOD write layer is magnetically sensitive. 

In conclusion, the analysis performed allows choosing better processing conditions and design solutions for magnetic sensitive and recording media based on a PAA/magnetic nanocomposite. 

They arc made of a laminated melaminealkyd core encapsulated in polyethylene wax. The core is colour coded by the inclusion of pigments. One of the layers contains iron particles to make the taggant magnet-sensitive and one or both exterior layers contain fluorescent compounds which respond to ultraviolet radiation.

Diradical species 296-299, in which two nitronyl nitroxide (ONC = NO) or imino nitroxide (NCNO) radical centres are bound to the thieno[2,3-Z)]thiophene and thieno[2,3-Z)]thieno[3, 2 -d]thiophene chromophores, were investigated. Their intramolecular exchange coupling in frozen solutions and the magnetic sensitivity at low temperatures were examined by ESR spectroscopy (95TL5543, 96T6893).
